Book report: Theory of Games and Economic Behavior (von Neumann & Morgenstern)

Thanks for the references! I now know that I'm interested specifically in cooperative game theory, and I see that Shoham & Leyton-Brown has a chapter on "coalitional game theory", so I'll take a look.

Conflict vs. mistake in non-zero-sum games

If you have two strategy pairs , you can form a convex combination of them like this: Flip a weighted coin; play strategy on heads and strategy on tails. This scheme requires both players to see the same coin flip.

Why you should minimax in two-player zero-sum games

A proof of the lemma :

Multi-agent safety

Ah, ok. When you said "obedience" I imagined too little agency — an agent that wouldn't stop to ask clarifying questions. But I think we're on the same page regarding the flavor of the objective.

Multi-agent safety

Might not intent alignment (doing what a human wants it to do, being helpful) be a better target than obedience (doing what a human told it to do)?

Stop saying wrong things

Also Dan Luu's essay 95%-ile isn't that good, where he claims that even 95th-percentile Overwatch players routinely make silly mistakes, suggesting that you can get to that level by not making mistakes.

Conflict vs. mistake in non-zero-sum games

Oh, this is quite interesting! Have you thought about how to make it work with mixed strategies?

I also found your paper about the Kripke semantics of PTE. I'll want to give this one a careful read.

You might be interested in: Robust Cooperation in the Prisoner's Dilemma (Barasz et al. 2014), which kind of extends Tennenholtz's program equilibrium.

Jan Bloch's Impossible War

Ah, thank you! I have now read the post, and I didn't find it hazardous either.

Jan Bloch's Impossible War

More info on the content or severity of the neuropsychological and evocation infohazards would be welcome. (The WWI warning is helpful; I didn't see that the first time.)

Examples of specific evocation hazards:

  • Images of gore
  • Graphic descriptions of violence
  • Flashing lights / epilepsy trigger

Examples of specific neuropsychological hazards:

  • Glowing descriptions of bad role models
  • Suicide baiting

I know which of these hazards I'm especially susceptible to and which I'm not.

I appreciate that Hivewired thought to put these warnings in. But I'm kind of astounded that enough readers plowed through the warnings and read the post (with the expectation that they would be harmed thereby?) to cause it to be promoted.

Conflict vs. mistake in non-zero-sum games

Oh I see, the Pareto frontier doesn't have to be convex because there isn't a shared random signal that the players can use to coordinate. Thanks!
